Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent damage of anode by discharge shock and interference with other devices by providing, in a vacuum casing, attenuating resistance to the tube current across the high voltage connection and the anode. SOLUTION: In a vacuum casing 2, a support shaft 6 is driven by a stator 13 and a rotor 12 to heat the heat coil 3 to supply a tube current IR to the high voltage connection 9 to flow through the heat coil 3.

Title: Heat-reflective coating and method of film deposition for it
Inventor: YONEKURA MASAAKI
IPC: C03C17/22
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a titanium nitride film of face-centered cubic structure, where the lattice spacing of a specific plane is within a specified range and excellent heat-reflecting function and high durability are provided, by controlling the amount of sputter gas introduced at sputtering by means of partial pressure and carrying out film deposition while keeping the surface of a Ti target in a state of metal/nitride transition region. SOLUTION: The titanium nitride film of face-centered cubic structure has 2.439-2.464 Å lattice spacing of the (111) plane. Preferred specific resistance of this film is <=2.3×10-4 Ω.cm. Suitable partial pressure of nitrogen gas at sputtering is 4.0×10-4 to 1.2×10-2 Pa, and also suitable total gas pressure and power density are 4.0×10-2 to 1.3×10-1 Pa and 3.0 W/cm2, respectively. When sputtering is performed at the partial pressure in the above range, the surface of the Ti target is in a transition mode and film deposition becomes unstable. However, stable film deposition can be done even in the transition mode by controlling the amount of nitrogen gas introduced so that the partial pressure becomes constant. It is desirable to use a transparent substrate as the substrate to be coated with the titanium nitride film.
